Notes: [Series title: Fauna of New Zealand; No. 41] The adult females of all Coccidae (Hemiptera: Coccoidea) known from new Zealand are described and illustrated. In addition to the four indigenous genera previously known (Ctenochiton, Inglisia, Lecanochiton and Pounamococcus), seven new genera are described (Aphenochiton, Crystallotesta, Epelidochiton, Kalasiris, Plumichiton, Poropeza and Umbonichiton), all of which are considered to be fairly closely related to Ctenochiton and all endemic to New Zealand. Within these eleven indigenous genera, 25 new species are described and 12 species are transferred to new genera, bringing the total to 43 species. Ctenochiton elongatus Maskell is designated a nomen dubium. None of the species currently included in the genera Ctenochiton and Inglisia described from outside new Zealand are here considered to be congeneric. In addition, all known adventive (exotic) species found in New Zealand are reviewed and briefly described. Lecanium (Eulecanium) spinosum Brittin is synonymised with Parthenolecanium persicae (Fabricius), and the synonymy of Lecanium cassiniae Maskell with Saissetia oleae (Oliver) is upheld. Pulvinaria psidii (Maskell) has not been recorded in New Zealand and its inclusion in previous checklists is erroneous. Keys to adult females are included for the separation of all genera and species, and also for preliminary instar separation. Earlier work done on the superfamily Coccoidea in New Zealand is briefly reviewed and the present classification of the Coccidae and closely related families is outlined. Their biology, distribution, host-plant interactions, parasites and predators, and economic importance are also described. The current methods for collecting and mounting specimens on slides for the New Zealand Arthropod Collection are outlined, followed by a description of the morphology of adult female Coccidae, introducing the terminology used. A list of host plants is included in an appendix.
